W0811 18:55:44.980177 2901 device_context.cc:259] Please NOTE: device: 0, CUDA Capability: 35, Driver API Version: 9.0, Runtime API Version: 8.0 W0811 18:55:44.989336 2901 device_context.cc:267] device: 0, cuDNN Version: 6.0. W0811 18:55:44.989390 2901 device_context.cc:293] WARNING: device: 0. The installed Paddle is compiled with CUDNN 7.1, but CUDNN version in your machine is 6.0, which may cause serious incompatible bug. Please recompile or reinstall Paddle with compatible CUDNN version. Load pretraining parameters from models/base/uncased_L-12_H-768_A-12/params. WARNING:root: You can try our memory optimize feature to save your memory usage: # create a build_strategy variable to set memory optimize option build_strategy = compiler.BuildStrategy() build_strategy.enable_inplace = True build_strategy.memory_optimize = True

     # pass the build_strategy to with_data_parallel API
     compiled_prog = compiler.CompiledProgram(main).with_data_parallel(
         loss_name=loss.name, build_strategy=build_strategy)

 !!! Memory optimize is our experimental feature !!!
     some variables may be removed/reused internal to save memory usage,
     in order to fetch the right value of the fetch_list, please set the
     persistable property to true for each variable in fetch_list

     # Sample
     conv1 = fluid.layers.conv2d(data, 4, 5, 1, act=None)
     # if you need to fetch conv1, then:
     conv1.persistable = True
